TYPE-SETTING MACHINE.

SPECIFICATION forming partof Letters Patent No. 717,960, dated January 6, 1903. Application filed June 21,1902. Serial No. 112.649. (N model.)

To all whom it mayconcern:

Be it known that I, EDWARD AUGUSTUS AD- COCK, a subject of the King of Great Britain and Ireland,residing atReading,in the county of Berks, England, have invented Improvements in or Relating to Type-Setting Machines, of which the following is a specification.

This invention has for object to enable the type-pushe rs used in some constructions of type-setting machines for. ejecting type from type-channels to be operated by power, the bringing intoaction ofthe respective pushers being-under the control of key mechanism,

so that the work of operating the key mechanism' shall be rendered much easier than is the casewhen the pushers are directly actuated from the keys and so that the complete movement of the pushers shall be insured at each operative stroke thereof.

The invention consists for this purpose in the combination, with each type-pusher and reciprocating means (hereinafter called a carrier) therefor, of a power-driven actuat ing device, a power-transmitting device, and a key-operated device, the arrangement being such that normally the power-transmitting device will be in a position in which the powerdriven actuating device will be out of operative connection with the carrier, but upon depressing the corresponding key the powertransmitting device will be caused to assume a position in which the said actuating device will operate the carrier in such a way as to cause the pusher to make its operative stroke and eject a type, the various parts afterward automatically resuming their. original positions ready to again go through the same cycle of operations when the key is again operated.

The invention also consistsin various novel features of construction and in combinations and arrangements of parts, all as hereinafter described, and pointed out in the claims.

In the accompanying illustrative drawings, Figure lis a vertical section on the line A A of Fig. 2; and Fig. 2 is a sectional plan on the line B B of Fig. 1, showingpart of a typesetting machine with type-pushers and conder the action of a weight f, the foremost type in each row being raised above the stop 0 at the required times in order that it may fall into the discharge-passage b by a verticallymovable type-pusher gin a manner now well understood and forming no part of the present invention. Each type-pusher g, accord ing to the present invention, is reciprocated by a power-driven actuating device, for which purpose it is connected to one end of a carrier h, which in the example is in. the form of a lever that is pivoted at its other end to a suitable bearing or support, shown as a rod 1', and is normally held in its lowest position. by a spring is. Extending transversely below. the several levers h, which are arranged side by side and at a convenient distance apart, is a plate m, that is mounted at one end to turn about a horizontal axis at n and is arranged to be operated-for example, as by rods 0 and eccentrics p-from some movable part of the machinefor example,a shaft q, that is driven by power-so that when the machine is in operation the said plate m will be caused to swing alternately toward and from the under side of the set of levers h independently of the operator of the machine. Pivoted to each lever h at h* is a powertransrnitting device in the form of a plate or pawl r, (hereinafter called the pawl,) which is so formed and arranged, as shown, that when released it will fall into a position (shown in dotted lines) in which it will be in the path of the oscillating plate m, so that power will then be transmitted through it from the said oscillating plate m to the corresponding lever h, and thus to the corresponding type-pusher g, which is then caused to rise and make its operative stroke and cause the foremost type cl, for the time being, in the corresponding trough Ct to rise above the stop 0 and fall into the discharge-passage b. Pivoted upon a rod 3, below the levers h and to one side of each of such levers, is a bent key-lever t, the forward end of which is provided with an ordinary finger-key u and the rearward end of which is acted upon by a spring 1; and is so arranged in relation to the pawl a" that normally it acts to hold the said pawl in its raised and inoperative position clear of the oscillating plate m. In the example the pawl 'r is of approximately quadrant shape and is so pivoted that it tends to fallinto the operative position, (shown in dotted lines in Fig. 1,) and the adjacent end of the key-operated lever z, is adapted normally to bear against the periphery of the said pawl and hold the pawl in its raised and inoperative position. (Shown in full lines in Fig. 1.)

The travel of each pawl 1' may be limited by a stop to on the corresponding lever h, the under side of which maybe recessed, as shown at h, to accommodate the oscillating plate m. Each lever h may also be provided with a stop a; to limit the upward movement of the inner end of the keylever 25, the upward movement of the outer end of which may be limited by a stop y on the frame 2 of the machine.

The operation of the arrangement above described is as follows: Upon depressing a key it, and with it the forward end of the corresponding key-levert the rearward end of the said key-lever will rise against the action of the spring 22 into contact with the stop a; and release the pawl r, which will then fall into its operative position and into the path of the oscillating plate m, which on its upward movement will then act through the pawl to raise the corresponding lever h and pusher g and eject a type d, the rearward end of the said key-lever i, which is then relieved of finger-pressure, acting, if necessary, and by contact with the pawl to insure the falling of the latter into the operative position should it have any tendency at any time to remain in its inoperative position when released by the key-lever. As soon as the upper edge 1" of the pawl r in its upward movement with the lever It becomes clear of the key-lever t the latter will return to its normal position under the action of its spring 7. and will be ready to again engage the pawl before the lever h has quite reached the end of its downward movement under the action of its spring is, the remaining portion of the downward movement of the said lever h causing the pawl to move clear of the oscillating plate on, and so allow of the latter making its next upstroke without actuating the lever 71. and pusher g unless the key-lever t be again immediately depressed. Should the pawl r be not quite clear of the oscillating plate m when it is released by the key-lever t, owing to the plate on being at the time in its upper position, the said key-lever on its return movement will keep the lower edge r of the pawl in contact with the free edge of the oscillating plate m until it becomes clear thereof by reason of the descent of the plate, whereupon it will at once move into the path of the oscillating plate, so that the cycle of operations can again take place as before.

It will be evident that various changes can be made in the details of construction of my apparatus without departing from the spirit and scope of the invention, so long as the relative arrangement of parts shown in the drawings or the mode of operation described in the specification is preserved.

What I claim is 1. In a type-setting machine, the combination witha type-magazine and a type-ejector for removing type therefrom, of a lever connected to said type-ejector, a pawl pivoted to said lever and having a constant tendency to fall into its operative position, means under the control of a finger-key for normally engaging with and holding said pawl in its raised and inoperative position, but capable when operated of releasing said pawl and allowing the same to fall into the operative position, and a power-driven actuating device arranged to actuate said pawl when the same is in its operative position and cause said lever and type-ejector to make their operative stroke.

2. In a type-setting machine, the combination with a type-magazine and a type ejector for removing type therefrom, of a lever connected to said type-ejector, a pawl pivoted to said lever and having a constant tendency to fall into its operative position, a key-lever pivoted below and arranged at one side of said first-mentioned lever and having its rearward end arranged to normally hold said pawl in its raised and inoperative position, and a power-driven actuating device arranged to actuate said pawl when the same is in its operative position and cause said first-mentioned lever and type-ejector to make their operative stroke.

3. In a type-setting machine, the combination with a plurality of type-troughs, and a plurality of reciprocatory pushers for ejecting type therefrom, of a plurality of carriers in the form of levers pivoted at one end, arranged side by side and each connected to one of said pushers, springs for normally holding said carriers in their lower position, a plurality of pawls each pivoted to one of said carriers so as to turn about a horizontal axis, a plurality of key-operated spring-pressed levers each having one arm arranged in proximity to the periphery of one of said pawls so as normally to hold such pawl in its inoperative position and when operated, to release such pawl and allow the same to fall into the operative position, and an oscillatory plate mounted to swing below said carriers and raise any pawl that may have fallen into its IIO operative position and also the corresponding carrier and type-pusher, substantially as described.

4. In .a type-setting machine, the combinaw tion with each type-trough and type-pusher, of the leverhpivoted to the frame of the machine, connected to said type-pusher and provided with stops w and 0a, a spring for normally holding said lever in its lowered posi- 10 tion, the pawl pivoted to said lever, the

I spring-pressed key-operated lever 13, the oscillating plate m, and means for continuously oscillating said plate, substantially as described.
